| Popis: | Barrier coverage is one of the research hot spots of wireless sensor network coverage control. In order to fix the defects and deficiencies of the network, which is composed of all isomorphic nodes in the barrier coverage, Voronoi diagram is introduced to divide the entire deployment area. According to the principle of the least square method, a mixed network deployment mechanism consisting of static nodes and dynamic nodes is established with static nodes working as the reference barrier line. By monitoring whether there is a barrier covering the blind spot in the deployed area, the monitoring area can be effectively covered by determining whether dynamic nodes need limited movement to redeploy the monitored area. And puts forward mixed node barrier covered in this algorithm, algorithm Voronoi diagram was used for continuous path problem domain discretization, and from different dimensions to compare coverage performance of each algorithm, the simulation experiments show that the algorithm improves the quality of monitoring area coverage, under the same conditions as other algorithms, a mobile node distance and low energy consumption, less expected to cover requirements and goals are met. |
